Fristam FKL PD Pump Helps Oskaloosa Food Products Improve Their Egg Processing

Founded in 1938, Oskaloosa Food Products provides dried, liquid and frozen egg products to the food industry. At Oskaloosa’s state of the art production facility in Oskaloosa Iowa, commitment to continuous improvement and product quality are two things they take very seriously.

When Fristam Pumps learned Oskaloosa’s existing PD pump required daily tear down for cleaning and was vibrating and cavitating, they approached them with a proposal to replace it with a Fristam FKL. The response from Oskaloosa President Blair Van Zetten was pretty straightforward: “Prove to us that your pump will handle all our fluid egg products gently and efficiently and effectively clean in place to USDA standards without teardown or disassembly.” The FKL was purchased with a performance guarantee that stated it would meet the above criteria or it could be returned to Fristam at no charge.

“The benefits of the FKL pump have exceeded our expectations....we’ve replaced every critical process pump in our facility with a Fristam FKL.”

Wear and damage from daily teardown for cleaning caused Oskaloosa’s existing pump to have poor suction capability and lead to cavitation. Because Fristam’s FKL Series positive displacement pumps are CIP’able those concerns were eliminated and Fristam’s FKL positive displacement pump handled every product (whole egg, salted yolk, sugar yolk, and yolk blends) gently and efficiently as promised. The tight tolerances of the FKL pump and its patented balanced rotor design give the pump excellent suction capability resulting in reduced cavitation and extremely high efficiency.

Van Zetten was interested in a change that could save time and money and alleviate performance issues. “At first, we were simply interested in improving pump life and reducing maintenance costs. The existing pumps were producing severe vibration and pulsation and we were only getting about six months of operation between rebuilds on some of the more difficult applications. The FKL pump has eliminated virtually all vibration,” which improves the life and operation of the pump, as well as other equipment in the process.

The pump that the Fristam FKL replaced required daily teardown and removal of rotors to be cleaned. USDA inspection and verification of cleanability was required on a daily basis as well. Designed to be cleaned in place, the FKL pump requires no teardown or rotor removal to be CIP’d. By simply running the pump during the CIP cycle (with a bypass to take the excess flow) the FKL proved that it cleans up extremely well, saving the maintenance of teardown and improving the repeatability and overall effectiveness of the CIP process.

“(The Fristam FKL) proved to clean perfectly and drastically reduce our maintenance costs and downtime for cleaning or rebuilding.”

After several weeks of daily USDA inspections for cleanability, the FKL pump continually met all requirements which allowed for a subsequent reduction in the inspection frequency from daily to weekly. “It has also proved to clean perfectly and drastically reduce our maintenance costs and downtime for cleaning or rebuilding,” remarked Van Zetten.

Process conditions met, and thoroughly impressed with the performance, cleanability, and reliability of the Fristam FKL, Oskaloosa Food Products purchased the trial pump along with a second FKL pump almost immediately. According to Van Zetten, “The benefits of the FKL pump have exceeded our expectations to the extent that within a year of the first install, we’ve replaced every critical process pump in our facility with a Fristam FKL.”

Fristam Pumps USA continues to live up to its reputation as a pump manufacturer that supplies processors with quality products engineered to deliver many years of reliable service and provide pumping solutions that reduce ownership costs and improve their bottom line.
